1. Router WAN IP address – This is the IP address provided by your ISP to access the Internet. This WAN IP address will also be used to access the PC providing the service. In this example, the Router WAN IP address is “123.123.123.123”.

Before setting up port forwarding for a FTP server, a PC on the Internet cannot connect to the FTP server.

Under the Basic Config section, select “FTP” from the “Famous Server List” item. Input a port or port range for the FTP server and select the Local IP.

In this example, the Server LAN IP address is “192.168.1.103“.

Click on “Edit” and then click on “Apply“.

Note: Do not use the port range 20:21 for an FTP server if the AiDisk service on the router has been enabled.

The FTP server is now running using the following settings:
Host: 123.123.123.123
Port: 2021

Source Target

Rules that only the IP address can be forwarded for the match port

For Source IP address, you can:

(a) Leave it empty. Unspecified, that is, any source IP can.

(b) Enter a specific IP address, such as “192.168.122.1”

(c) Enter IP address within one subnet or the same IP pool, such as “192.168.123.*”, or “192.168.*.*” or “*.*.*.*”

To check if Port Forwarding has successfully been configured for a FTP server:

Ensure that your FTP server is set up and running.

You will need a PC outside your LAN but has Internet access (hereafter referred to as “Internet PC”). This PC should not be connected to the ASUS router in any way.

On the Internet PC, use the router’s WAN IP to access the FTP server using a FTP application or FTP browser. If port forwarding has been successful, you should be able to access the files on the FTP server.

To set up port forwarding for a HTTP server:

Before setting up port forwarding for an HTTP server, a PC on the Internet cannot connect to your server/PC via HTTP.

Under the Basic Config section, select “HTTP” from the “Famous Server List” item. Input a port or port range for the HTTP server and select the Local IP.

In this example, the Server LAN IP address is “192.168.1.103“.

Click on “Edit” and then click on “Apply“.

The HTTP server is now running using the following settings:
Host: 123.123.123.123
Port: 80

Source Target: Rules that only the IP address can be forwarded for the match port

For Source IP address, you can:

(a) Leave it empty. Unspecified, that is, any source IP can.

(b) Enter a specific IP address, such as “192.168.122.1”

(c) Enter IP address within one subnet or the same IP pool, such as “192.168.123.*”, or “192.168.*.*” or “*.*.*.*”

To check if port forwarding has successfully been configured for an HTTP server:

Ensure that your HTTP server is set up and running.

You will need a PC outside your LAN but has Internet access (hereafter referred to as “Internet PC”). This PC should not be connected to the ASUS router in any way.

On the Internet PC, launch a web browser and key in the router’s WAN IP address on the address bar. If port forwarding has been successful, you should be able to access the web page provided by the HTTP server.

**If you want to forward a port range, for example 10200:10300, to a PC which is using the same port range, enter the service name, port range, and local IP address, but leave the local port blank.

Enable WAN: Enable and disable WAN. Under some connection types, you can get a new IP address by using Enable and Disable WAN.

Enable NAT: NAT(Network Address Translation) is a process used in routers to replace the address information of network packets with new address information. Typical applications for NAT is for routers which connect to LAN with the WAN. In LAN, every network device had a private IP (LAN IP) but there’s only one public IP (WAN IP). To grant internet access to the network devices, the router replaces the private IP address of the sender with its own public IP address in all outgoing data packets. The router saves all necessary information in a table (NAT table) so that incoming data packets can then be assigned to the correct network device.

Enable UPnP: UPnP(Universal Plug and Play) allows several devices(routers, televisions, stereo systems, game consoles, cellular phone) to be controlled via an IP-based network with or without a central control through a gateway.

Authentication: This item may be specified by some ISPs. Check with your ISP and fill them in if required.

Host Name: You can provide a host name for your router. It’s usually requested by your ISP.

MAC Address: MAC(Media Access Control) address is a unique identifier that identifies your computer or device in the network. ISPs monitor the MAC addresses of devices that connect to their services, and would disallow Internet Connection for new MAC addresses. To fix this issue, you can do either of the following:
* Contact your ISP and request to update the MAC address associated with your ISP subscription.
* Clone or change the MAC address of the new device to match the MAC address of the original device.

DHCP query frequency: Some Internet Service Providers block MAC addresses if the device makes DHCP queries too often. To prevent this, change the DHCP query frequency.
In the default Aggressive mode, if the router does not get a response from the ISP, it sends another query after 20 seconds and then makes three more attempts.
In Normal mode, if the router doesn’t get a response from the ISP, it makes a second query after 120 seconds and then makes two more attempts.

Enable WAN: Enable and disable WAN. Under some connection type, you can get a new IP address by enable and disable WAN.
